According to the Brønsted-Lowry theory, an acid is any substance (molecule or ion) that
can transfer a proton (H ion) to another substance, and a base is any substance that
can accept a proton. Acid-base reactions are proton-transfer reactions, as follows:
HA +
= BH! + A

Part D
Chemical species whose formulas differ only by one proton are said to be conjugate acid-
base pairs. Thus, A is the conjugate base of the acid HA, and HA is the conjugate
acid of the base A Similarly, B is the conjugate base of the acid BH, and BH is
the conjugate acid of the base B. The stronger the acid, the weaker the conjugate base,
and the stronger the base, the weaker the conjugate acid.
Among three bases, X, Y, and Z , the strongest one is Y, and the weakest one is Z . Rank their conjugate acids, HX, HY, and HZ, in order of decreasing strength.
Rank the acids from strongest to weakest. To rank items as equivalent, overlap them.
